查询某个指定服务进程名称的全部 PID 值，然后打印在标准输出中
pidof [-s] [-c] [-n] [-x] [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] program [program..]| 参数 | 作用 |
|---|---|
| -s | Single shot - this instructs the program to only return one pid. |
| -c | Only return process ids that are running with the same root directory. This option is ignored for non-root users, as they will be unable to check the current root directory of processes they do not own. |
| -n | Avoid stat(2) system function call on all binaries which are located on network based file systems like NFS. Instead of using this option the the variable PIDOF_NETFS may be set and exported. |
| -x | Scripts too - this causes the program to also return process id's of shells running the named scripts. |
| -o omitpid | Tells pidof to omit processes with that process id. The special pid %PPID can be used to name the parent process of the pidof program, in other words the calling shell or shell script. |
- 0 - At least one program was found with the requested name.
- 1 - No program was found with the requested name.
- 输出 sshd 服务名的全部 PID
pidof sshd
3623 839- 输出指定进程名的一个 PID
sleep 10000 &
[1] 4900
pidof -s sleep
4900
